It is very easy to install. All you have to do is put a small hole in you intake tube right next to the carburator, they provide a tool to make the hole the right diameter. This is where the dial a jet itself is put Then you have to remove the screw from the bottom of the float bowl of the carb and put in the provided hollow screw. Attach the hose from the screw in the float bowl to the dial a jet and you done. And i would also reccomend the snorkel kit they sell to keep water and dirt out of you engine.
